GBBE Unit 1 TEST WITHCOMPLETE SOLUTION
Study of inherited traits and their variation is. - ANSWER Genetics
Passing of traits and biological information between generations is. -
ANSWER Heredity
A set of instructions for cells to make specific proteins for the control of
some characteristics is. - ANSWER Gene
A complete set of genetic instructions for the characteristics of an organism
is. - ANSWER Genome
A gene is specific proteins and the characteristics that they create for an
organism is. - ANSWER DNA sequence
The field of study that addresses moral issues and controversies that arise in
new medical technologies created today is. - ANSWER Bioethics
What are the levels of genetic information? - ANSWER 1. It starts at a
molecular level, 2. Goes through cells, tissues and organs, 4. Goes though
organisations and individuals, families, population 5. Species
How does DNA carry and maintain information? -ANSWER DNA is in the
form of a helix, composed of chemical bases. These include: (A)Adeline,
(T)Thymine, (C)Cytosine, and (G)Guanine. These sequence of bases help to
carry the information to make proteins.
, How could a mutation result in disease? -ANSWER A mutation changes the
bases in DNA. If the DNA has changed, then the wrong amino acid is
produced for a protein. This means, instead of a normal protein an altogether
different protein is formed and it leads to disruptions in the system of cell
resulting in a certain disease.
How can it be said that a gene can exist in more than one form? - ANS Two
genes are composed of different DNA base sequences but can be made up of
the same amino acids. This results in having the same proteins and the same
exact gene; hence, the gene exists in more than one form.
What is the difference between a Mendelian and a multifactorial trait? -
ANSWER Mendelian traits are caused by a single gene whereas
multifactorial traits are caused by a minimum of 3 genes and other outside
influences such as environment.
How does gene expression underlie composition of the human body?
ANSWER Gene "expression", no matter how different they are, all assemble
together to secrete nonliving materials to create compositions of the human
body, like cells, tissue, and eventually organs.
What is the difference between a genotype and phenotype? ANSWER A
genotype is a trait specific to the genes or alleles. A phenotype is a visible
